View Full Version : [ubuntu] flowchart generator

August 4th, 2010, 06:47 PM
Hi, I am using Ubuntu 10.04. I am currently learning C, and was wondering if there was any open source software which could create a flowchart for a C program. Can anyone suggest the best one if there are any?

I know that using Data Display Debugger we can run through the program flow, but a flowchart maker would also be invaluable.

DIA is pretty good (http://www.linux.com/learn/tutorials/289802:creating-flowcharts-with-dia) and is in synaptic ......

What you want is an automated code parser that creates a flowchart from somebody's code. I don't know of any offhand, but there are some UML tools (Unified Modeling Language) that will read C code and create Class connection diagrams. It's not exactly a flowchart, but it will help parse a complex software project.

This is one that I have used:

DDD's going to operate on the program dynamically (i.e. with real program inputs).

If you're more interested in the dynamic behavior of a program, rather than the static properties of the code, then you'll want to generate the callgraphs of the application.

Kcachegrind is an intuitive profiler which can also visualize the callgraphs for a program run. This is useful because it not only shows you the connections in a program, but it also tells you where most of the time is spent in the program.

Kcachegrind will generate an output that looks like this (http://sandroandrade.files.wordpress.com/2009/04/kcgshot3large.gif). It is available in the repos via:

sudo aptitude install kcachegrind
